Claims. (Cl. 5-317) In the normal routine, an invalid must be gotten from bed to a wheelchair and back again frequently. As a rule, that operation involves rising from a sitting position to a standing position, turning, and sitting down again, which is laborious, fatiguing, and dangerous.

The principal object of this invention is to make those movements relatively easy and safe.

Generally speaking, this is accomplished by providing a light, sturdy turnstand or transfer stand that can be readily placed between a bed and a wheelchair on which the patient may rise, stand, and be turned, and then sit down on a bed or wheelchair, as the case may be. An automatic lock prevents turning except when intentionally done and while forcibly unlocked.

Further objects and advantages of the invention will appear as the description is read in connection with the accompanying drawings, in which:

Fig. 1 is a diagrammatic, perspective view illustrating one position of the bedside stand, a bed, a wheelchair, and a patient;

Fig. 2 is a similar view with the patient on the stand and a nurse in the act of releasing the lock;

Fig. 3 is a perspective view of the turnstand;

Fig. 4 is a plan view;

Fig. 5 is a section on the line 55 of Fig. 4; and

Fig. 6 is an enlarged section on the line 66 of Fig. 4.

As best shown in Fig. 5, the device includes a circular bottom plate or base 10 supporting a circular top or tread plate 11 on roller, needle, or ballbearings 12, and swivelled to it by a depending gudgeon 13 extending downwardly from the top plate through a bearing opening 14 in a boss 15, and made fast by a screw 16 having a head 17 received within the counterbore 18. 7

Around the margin of the top or tread plate 11, there is a downwardly inclined flange 19 slotted to form teeth 20 for engagement with a combined latch and handle 21 having inturned end portions 22 pivoted in lugs 23 on the bottom plate and having side arms 24 fulcrumed at 35 and adapted to engage the teeth 20.

Secured to and rising from the top plate 11 is a combined handhold and steadying rail, generally indicated by 25, consisting of a loop of tubing having the ends made fast at 26 to the top plate and having three bends 27, 28, and 29 by which it is provided with inset vertical portions 30 and upper and lower horizontal portions 31 and 32, which serve as handholds and steadying or side rails for the patient.

In use, the device is pulled into position beside the invalids bed (for example, as shown in Figs. 1 and 2), the combined handle and lock making that movement comparatively easy and convenient.

Assuming the patient is to be transferred from the wheelchair (shown in Fig. 1) to the bed, the initial relation may be as shown in Fig. 1, or with the wheelchair and turnstand may be at 90 degrees to the position they appear there.

The patient moves his feet, or has them moved, from the step of the wheelchair to the tread plate 11, and

2,757,388 Patented Aug. 7, 1956 by his own strength, or with the assistance of the nurse, comes to a standing position with his hands on the guard rail and his body guarded by the loop of the guard rail.

The nurse then uses the handle as a treadle to unlock the tread plate and swings the patient to a position to sit on the bed, and then releases the handle, which immediately locks the tread plate in position, and the patient may safely sit down on the bed with or without the assistance that may be appropriate.

In moving the patient in the opposite direction, it will be apparent from Figs. 1 and 2 that the operation is substantially reversed.

I claim:

1. An invalids transfer stand comprising a base, a generally horizontal and circular tread plate rotatably mounted on said base, an upstanding handhold and steadying rail fixed to said plate, said rail comprising a generally U-shaped element having the ends thereof fixed in spaced apart relation adjacent the periphery of said plate and having its web curved concentrically with respect to said plate about the axis of rotation of said plate, said plate being formed with a plurality of recesses about its periphery, an upwardly biased latch carried by said base and positioned to cooperate with said recesses to preclude movement of said plate, and treadle means fixed to said latch and extending radially outwardly of said plate.

2. The transfer stand set forth in claim 1 wherein said rail is formed to extend above and about approximately one-half of the periphery of said plate.

3. An invalids transfer stand comprising a base, a generally horizontal and circular tread plate rotatably mounted on said base, an upstanding handhold and steadying rail fixed to said plate, said rail comprising an upright member fixed to said plate and including a generally horizontal portion concentrically curved with respect to said plate about the axis of rotation of said plate and extending at least degrees about said plate, said plate being formed with a plurality of recesses about its periphery, and an upwardly biased latch carried by said base and positioned to cooperate with said recesses to preclude movement of said plate with respect to said base, said latch including treadle means extending radially outwardly of said plate, whereby said latch may be depressed by stepping on said treadle means to release said plate for rotation with respect to said base.

4. An invalids transfer stand comprising a base, a generally horizontal and circular tread plate rotatably mounted on said base, and an upstanding handhold and steadying rail fixed to said plate, said rail comprising a generally U- shaped member having the ends thereof fixed in spaced apart relation to said plate and having the upwardly extending ends of its legs and its web curved concentrically with respect to said plate about the axis of rotation of said plate approximately 180 degrees thereof, said legs and said web of said rail thereby defining vertically spaced horizontally extending hand gripping portions, said plate being formed with a plurality of recesses about its periphery, and an upwardly biased latch carried by said base and positioned to cooperate with said recesses to preclude movement of said plate with respect to said base, said latch including treadle means extending radially outwardly of said plate, whereby said latch may be depressed by stepping on said treadle means to release said plate for rotation with respect to said base.

5. The transfer stand set forth in claim 4 wherein said base is formed with lug means, and wherein said latch comprises a generally U-shaped element having its legs mounted in said lug means for pivotal movement about References Cited in the file of this patent UNITED STATES PATENTS Letters Nov. 29, 1904 Smelker Sept. 4, 1928 Saunders June 13, 1944 Josephs July 20, 1948 Stewart Mar. 28, 1950
